I've finally get the RE Archives working. I was able to get hold of an NTSC copy, works like charm in my wasabi dx even the GH Metallica. I'm not sure though why is it not reading the PAL version. I have other PAL games working though.

Sometimes the out of region games will give you trouble. Best fix, if the game is available in your region, download that one.

On another note be sure not to update you wii to 4.2 or non of your out of region games will work with your chip.
